What nobody tells you
- A will has to be executed according to your jurisdiction's formal requirements (witnesses, sometimes notarization) or it can be challenged or thrown out entirely.
- You can write a valid simple will yourself for a straightforward situation, but complexity (blended families, a business, property in multiple places) usually needs a lawyer.
- A will only controls assets that don't already have a beneficiary designation or joint ownership — it doesn't override those.
The basics
- An executor is the person legally responsible for carrying out your will's instructions after you die.
- A guardian, named in the will, is who you want to raise your minor children if both parents are gone.
- Witness and signing requirements vary by state and country — a will not properly executed can be invalidated regardless of its content.
The framework
Who, what, who's in charge
Every will answers three core questions. Get clear, specific answers to each before worrying about legal language.
- 01
Who gets your assets, and in what proportions or specific bequests?
- 02
What happens to any minor children — who is the named guardian?
- 03
Who is in charge of executing all of this, and do they know and agree to the role?
The playbook
Words they use without explaining
- Codicil
- A formal amendment to an existing will, used for smaller changes without redoing the whole document.
- Residual estate
- Everything left after specific bequests are distributed, usually divided among named beneficiaries.
- Testator
- The legal term for the person whose will it is.
The mistakes — what people get wrong
- Using a beneficiary who is also a witness to the signing — in many jurisdictions this can void their inheritance or the whole document.
- Writing a will and never telling the named executor or guardian — surprise appointments can lead to refusal or conflict later.
- Assuming an old will from a previous marriage or life stage still reflects your current wishes.
Ask yourself
- Have I actually asked my chosen executor and guardian if they're willing to take on the role?
- Does my will reflect my current life, or an earlier version of it?
- Do I know my jurisdiction's specific signing and witnessing requirements?
